Question

identify the vertex and the axis of symmetry for the graph of y=-5(x-2)^2+4

Answer 1

Vertex (2,4)
Axis of symmetry =2

Answer 2

how did you find the axis of symmetry?

Answer 3

From your equation
y=-5(x-2)^2+4

(x-2)=0
x=2

Answer 4

The vertex form of a quadratic is given by y = a(x – h)2 + k, where (h, k) is the vertex.
